    摘要： An apparatus for controlling a hybrid vehicle having an internal combustion engine and an electric motor as driving sources for the vehicle, in which when it is detected that an air-fuel ratio of a supply air-fuel mixture to the engine changed to the lean side value (S44˜S46), the electric motor (2) is made operative as a motor in order to assist an output of the engine just after the detection (S47, S48). When it is detected that the air-fuel ratio of the supply air-fuel mixture changed to the rich side value (S44, S52, S53), the electric motor (2) is made operative as a generator for the purpose of the regeneration braking just after the detection (S54, S55). An output torque difference of the engine, therefore, when the air-fuel ratio of the supply air-fuel mixture changes can be sufficiently compensated without a time delay.

    摘要： An abnormality detection system is provided, which detects abnormality in an evaporative fuel control system for an internal combustion engine. A plurality of temperature sensors are arranged in an evaporative fuel storage device at different locations for detecting the temperature of an adsorbent or in the vicinity thereof within the storage device at the different locations. An ECU controls at least one of charging of evaporative fuel from the fuel tank to the storage device and purging of evaporative fuel from the storage device to the intake system of the engine. The ECU determines the presence or absence of an abnormality in the evaporative fuel control system, based upon output values from the temperature sensors assumed when the control system is operative. A state in which adsorption of evaporative fuel generated in the fuel tank to the adsorbent of the storage device has been completed is detected, based upon the amount of a rise in temperature detected while the charging is being effected. The ECU effects the abnormality determination after the state has been detected. The system may be applied to an internal combustion engine in which the air-fuel ratio is controlled by the use of an air-fuel ratio correction coefficient determined in response to an output from an air-fuel ratio sensor.

    摘要： An auxiliary air amount control system for an internal combustion engine has an auxiliary air passage bypassing a throttle valve arranged within the intake pipe of the engine, and a control valve controlling the amount of auxiliary air supplied to the engine through the auxiliary air passage by varying the opening of the passage. The opening of the control valve is set in response to the opening of the throttle valve, and is decreased progressively from the set value as an initial value when the engine is in a predetermined decelerating condition. The set control valve opening is varied to a larger value as the reduction ratio assumed by a transmission connected to the engine is larger. The minimum value of the throttle valve opening at which the control valve opening can be set to a value larger than zero is varied to a smaller value as the reduction ratio is larger. The rate at which the control valve opening is progressively decreased is varied to a smaller value as the reduction ratio is larger.
